Update timeline

  1. investigating Aug 21, 2025, 07:05 PM UTC

    As of approximately 6 p.m. UTC, edX systems including but not necessarily limited to the learner dashboard and the in-course experience are experiencing slower performance than is typical. We are currently investigating the cause of this issue.

  2. resolved Aug 21, 2025, 11:38 PM UTC

    The latency issues across edX have been resolved and all services should now be operating normally. The issues appear to have been caused by one of our service providers, Cloudflare, which experienced degraded performance today, impacting applications across the internet.
